i think it's fun sometimes! if i see a light turn red like way down the road with nothing ahead of me i might pop the selector into E to get a super long coast without any engine braking
btw i assume your W223 does this too but the GLE (450 model at least) will actually do variable regen depending on how quickly the car in front of you starts slowing down, it's almost like dynamic cruise control but only acts on the ISG... i enjoy that too since if you get the timing right you can pretty much come to nearly a full stop without having to touch the brakes, although it does involve potentially tailgating a bit closer than most would be ok with lol

i've never experienced a "shudder" when the GLE does this, it's actually an exceptionally smooth engagement... if you weren't looking at the tach you really wouldn't know the engine turned back on and re-engaged with the drivetrain

SW's Valve Cover Gasket was gonna be what, 10 grand if paid out of warranty? It was some ludicrously stupid amount.
That's just labor bc the engine is so insanely complex. Adding all of this junk to it? Pass. Even worse.

I personally don't prefer or not prefer a 48v system. The reality is though that all new cars are going to have 48v systems, and I don't want to keep driving the same car so 48v it is. I feel the same way about EVs, more and more of the attractive cars are going to be EVs, so I'm open to EVs.
yes only in eco setting (E) will "glide mode" activate where it basically just goes into neutral on the move and kills the engine, and afaik the car never defaults to starting in E setting so if glide mode ever does activate it's because the car was manually put there

Thats just it, IMO this kind of improves the driving experience if anything. It fills in any turbo lag down low, and at a stop you have the total silence of an EV which is nice.
Except that adding this if anything reduces complexity...it doesn't increase complexity. Not gonna own it out of warranty anyways.

Explain to me how less wiring is more complex? And how many 48v systems has this "expert" worked on? And what does a Mercedes S Class Valve cover have to do with 48v? Opinions are OK, but uniformed ones hurt people, mainly themselves

I don't know much about "48 volt systems" on cars and what they're used for other than active suspension like posted above
But, I can see where upping to 48v can only help because smaller and lighter wires and motors can be used. It's a good thing because it helps with the higher power demands.
However, when someone says, " active suspension", I'm already expecting lots added complexity (both mechanical & electrical) when compared to dumb struts and control arms. Lol

They're actually not, if anything it reduces complexity. The issue with the 48v system is in the error processing and warning systems. They can wreak havoc from a software standpoint.

Yep, I have felt the same thing...its very cool.

Well the good news is you can still buy cars that don't have things like active suspension, and save a lot of money doing so. Cars like the S-Class are never going to be lacking in complexity. A partner at my firm recently traded his Lexus in for an Elantra because he just wanted a basic car that gets him from A to B and was done with all the features. Different strokes for different folks.

the ISG at the front eliminates the need for accessory belts and pulley driven pumps... for the latest, most cutting edge engine ever put into a production car it's really remarkably simple in its external appearance! gordon murray himself vouched for the 48V system and there's nobody who thinks more big picture than him in terms of a car remaining relevant and usable for the following decades

just to bring things to the totally opposite end of the spectrum: the V12 of the GMA T.50 is possibly the cleanest engine design ever thanks to 48V

EDIT
BTW, that IS the cleanest engine I've ever seen.....thanks to 48v

Hybrids have been around for 30 years, lots and lots of regular ol' mechanics are able to repair hybrids. As hybrids get older, even more of them will learn how and be able to...they will have to in order to remain in business.
BTW, nothing on the M176 engine with or without a 48v system is easily repaired by just any mechanic. You need a specialist.
